Description

[Detailed description of the invention] The present invention relates to a lumbar pillow that can stretch the lumbar region of the body by supplying compressed air and inflating it. This invention relates to a lumbar support pillow which is provided with a stabilizing member having a suitable elasticity and having a flat surface that conforms to the shape of the back surface of the lumbar region of the body.

A lumbar stretcher places a bag on the back of the lumbar region of a supine person, and intermittently supplies compressed air to this bag, causing it to expand and contract repeatedly to effectively apply elongated pine surges to the lumbar region. When compressed air is supplied to the body, the top of the bag expands into a round shape.
The lower back resting on this area tends to roll sideways. Therefore, a device was devised in which a sheet material with low elasticity was formed into a ring shape as the surface material of the bag body, and a sheet with high elasticity was joined in a tube shape along the inner surface of this ring-shaped sheet to form the whole into a ring shape. This allows the bag to rest on the waist better when inflated compared to a normal bag that expands into a barrel shape.

However, even if the surface material of the bag body is simply made of a material with low elasticity, it is impossible to make the top surface completely flat when it is inflated, and the reality is that the bag will bulge out somewhat. In order to place it stably on your body, you had to lightly support it with your hands and feet to maintain balance. Furthermore, when the body is moved on the inflated bag, an unbalanced force is applied to the bag, increasing instability, making it somewhat difficult to maintain a comfortable extended pine surge state.

The present invention is a lumbar pillow comprising a ring-shaped bag that intermittently supplies compressed air, and a stabilizing member having a flat surface that matches the shape of the back surface of the lumbar region attached to the central hollow part of the ring-shaped bag, and its purpose is to When the bag is inflated, the waist resting on the bag is stably supported by the stabilizing member, and even if the body moves on the inflated bag, the supporting force of the bag is less likely to become imbalanced, and the bag can be easily extended. To provide a lumbar stretching pillow capable of maintaining a pine surge state.

Hereinafter, the present invention will be explained with reference to an embodiment shown in the drawings.

Fig. 1 is an explanatory diagram of the use state of the lumbar extension pillow of the present invention, Fig. 2 is a perspective view of the lumbar extension pillow, Fig. 3 is a perspective view of the stabilizing member, and Figs. 4 and 5 are the same as Fig. 1. - line and - line sectional views.

The lumbar pillow of the present invention is comprised of a ring-shaped bag 1 that is inflated by compressed air, and a stabilizing member 2 with appropriate elasticity that is attached to the central cavity of the bag 1. The bag 1 includes a compressed air generator 3 shown in FIG.
It has a socket 6 to which an air supply pipe 4 connecting the bag body 1 and the bag body 1 can be detachably connected. Also, bag body 1
is a ring-shaped surface sheet material 1 with relatively low elasticity.
a, and a highly elastic back sheet material 1b whose both ends are joined to the inner surface of the top sheet material 1a to form a ring shape as a whole.

As shown in FIG. 3, the upper surface of the stabilizing member 2, which can be attached to the central cavity of the ring-shaped bag 1, has a groove-shaped curved depression 2 in the longitudinal center in accordance with the bulge of the back surface of the body S.
a, forming a rising part 2b with a gentle curvature toward the side end in the lateral direction, and a depression 2c with a relatively large curvature in accordance with the depression of the buttocks of the body at the lower part in the vertical direction. There is.

The stabilizing member 2 is attached to the bag 1 by inserting it into the central cavity of the bag while the bag 1 is deflated.
In this way, the lumbar pillow with the stabilizing member attached to the bag body 1 is placed on the back of the lower back as shown in FIG. Compressed air is delivered via pipe 4. In this embodiment, an air flow rate adjusting member 5 is provided in the middle of the supply pipe 4, and the user can press the adjusting member 5 to supply compressed air to the bag as desired.

When the bag 1 is inflated at the back of the waist, in the vertical direction shown in FIG. 4, the curved shape of the upper surface of the stabilizing member 2 presses against the back of the waist evenly, and in the horizontal direction shown in FIG. 2 side rising portions 2b, 2b
This supports the waist from the side, and even if the body S leans laterally, the air inside the bag wraps around below the stabilizing member 2 and evenly pushes up the stabilizing member 2 to keep the body balanced.

As mentioned above, the present invention has a curved surface that matches the shape of the back of the waist on the top surface of the stabilizing member 2, which is attached to the central cavity of the ring-shaped bag 1 that is inflated with compressed air. At the same time, it applies pressing force evenly to the back of the lumbar region, and the stable support force pushes up the lumbar region to perform effective elongation pine surgery. Since the internal air goes under the stabilizing member and pushes it up evenly, it is possible to maintain a comfortable elongated pine surge state at all times without making the body unbalanced. In addition, since the amount of compressed air supplied from the compressed air generator 3 can be appropriately adjusted by the adjustment member 5, the inflation force or the inflation time of the bag body can be stabilized in addition to the effect of the waist-stretching pillow provided with the above-mentioned stabilizing member. It has the advantage of being able to perform effective stretching pine surgery.
